How Water Enters Your Crawl Space
WATER PROBLEMS?
We Can Help!
Water comes in a Crawl Space from a number of ways. The most common entrance is through the wall where the first course of brick or block is laid. It also rises up through the ground if the water table is high and can create a pressure hole, where water literally shoots up because there is so much pressure in the ground.
** Most Crawl Space Water Problems come from lack of Roof Drains. (downspout drain line) The amount of water the roof gathers is tremendous! – – In average 1″ rain fall, a 2000 sq ft roof gathers 1100 gallons of water. If there is no Downspout Drain Line, this water is probably going into to your crawl space or basement.
The downspout drain is NOT just a 10 foot piece of pipe pointing out in the yard. PLEASE SEE DOWNSPOUT DRAIN for a better understanding.
To help remove water from your crawl space, look at the information below.

It helps to understand the construction of your homes foundation and understand that there is more than one type of foundation wall, but here are the basics: Most foundation walls sit on top of the footer. The footer is poured concrete usually 8 inches thick. It runs level around the perimeter of your home to support the house. Block and brick are used to build the foundation wall. The first course of brick or block sits in a bed of mortar used to level the first course. It here where most water enters the crawl space even if the outside has been sealed. Water also enters through the mortar used between bricks and block on up the wall anywhere the wall is below grade (underground). To collect the water, we need a system of gravel and perforated pipe along the inside of the crawl space with a discharge point for the water to escape. We like to use a sump pump for the discharge because it sits so deep in the crawl space, usually as deep as the bottom of the footer. The pump is fast, quiet and very reliable. Seeing a sump pump in a crawl space means The Water Problem has been Solved! You’ll find in most cities in the northern part of the country, that a sump pump is now code for building a basement. That’s how reliable they are! They are standard in building practice. Code here in Florida (lol – millions of codes right?) has no specific code written about crawl space drainage. Go Figure! Working in your crawl space can be a difficult task. There is very little room to move around, let alone trying to dig or excavate along your foundation footer. Here’s What We Do and How We Do it: Installing Foundations Drains (footer Tiles) 2nd – we grade out the excess soil across the crawl space floor leaving a small mound to help force the water into our system. 3rd– we bring in the gravel and the pipe. This is usually done one bucket at a time. Very labor intense. Depending on the length of the wall we working on, it might be 1 yard or more of 3/4 inch washed gravel commonly known as #67 stone. The buckets are 5 gallon type and we carefully move them over and under the pipes, around the piers until we get to the area we are working on. This process repeats! 4th – we then lay the perforated pipe (holes down) into a base of gravel at the bottom of the trench, then cover the pipe with gravel as well as the footer water ledge. The holes in the pipe point down because this in the way the system works, water floods upward through the voids in the gravel and into the holes of the pipe. If the holes are pointing upward, the water table simply rising way too high, and the trench holds too much water. 5th – We then cover the new trench with a vapor barrier and its done. Installing the Sump Pump 2nd – we remove the soil we just dug out for the sump pit. This is done one bucket at a time. very labor intense. 3rd – we install the sump pump. The pump sits at the bottom of the sump pit so as to allow water to collect and the pump will lift it up and out of the crawl space. Next we attach the discharge pipe which is 1 1/2 inch PVC and a check valve to prevent back flow. The pipe comes from the pump up and out through a solid lid cover where make cut a hole for the pipe to come through. this cover is very important. It stops debris and other things from falling into the pit and also reduces radon gas emissions! Cutting The Core Through The Foundation Wall We can cut through brick, block and even the footer made of solid concrete. Attaching the Discharge Line to the pipes outside 2nd – we test the pump discharge and check for leaks. If all is good, then we back fill and its done. |

Sump Pumps | A sump pump is the best way to remove water. Its fast, queit and very reliable.
We use Zoeller Pumps. Most commonly, Model M53 submersible with a 1/3 Horsepower motor, 1 ½ inch discharge line, and check valve to prevent back flow. To Date, we have not every been back to replace one of these pumps! That’s not to say they last forever, but they do last a long long time! |
 |
Sump Pits | A Sump Pit (the liner) is 24″ deep and surrounded by gravel to promote drainage into the pit. The pit is large enough to allow water to gather for the pump to lift it out. It comes witha solid lid cover to to help reduce moisture and radon gas!
|
 |
Cores | The Core is a hole drilled through the foundatin wall. The hole is usually 2″ which allows the 1 ½ inch PVC pipe to be inserted. Its a perfect fit! We can core walls, foundations, and curbs!
|
 |
Pipe | PVC Pipe is our choice for most drain lines. The solid pipe has smooth inside walls allowing water to easily flow through it. Size depends on the application. Downspout Drain Lines and Yard Drains, usually use 4 inch pipe. Storm Drains might use 6 inch or even 8 inch. |
 |
We also use Corrugated Pipe. This pipe is strong and comes in 100 foot rolls. It comes inSolid and perforated (holes in it). We use it for Yard Drains, French Drains, Foundation Drains and encase (surround) the pipe in gravel to help promote drainage.

   |
Trenching | Trenching is done with a Ditch Witch, a machine used to trench fast and effectively to the proper depth. We don’t make a mess! We lay our tarps to catch the soil. After we Back Fill the trench, we move the excess to low spots or foundation walls and grade it out.
We Also Hand Dig. Shovels and Picks are used to help prevent damage to Utilities, such as Telephone, Cable, Gas, Electric and Sprinklers. We call to locate utilities on every job. Utitlies are marked with paint and flags showing us where they are and allows us to adjust our installation accordingly.. |
  |
Concrete Work | Driveways, Basement Floors, Side Walks, Patio’s.. Concrete is not a problem for us to cut and repalce. We have the right tools for any job.
When we need to trench a line through a driveway, we simply cut out a trench about 8 inches wide, remove the concrete, dig down to install our pipe , backfill and re-pour the concrete. No Worries! You’ll be surprised how good it looks when we are finished. Concrete is actually one of the easiest things to trench through when you have the right equipment. No need to pay higher prices like others charge because they have to rent equipment. We Cut Concrete Everyday and We’ll Do It Right The First Time! |

This is best video that shows WHERE and HOW water enters your Crawl Space or Basement. We actually put the camera INSIDE a void in the wall.
We suggest you watch it a couple times. It will amaze you what we find when we dig down the outside of basement or crawl space wall…
Low spots in the backyard hold water. If there is no gravity or fall away from the area, that water will usually stand and stay there for days. This invites mosquitos and other insects as well as kill the sod, shrubs and eventually you have a big mud mess.
To solve this problem, a French Drain with catch basins leading to a sump pump, or small lift station, is needed. The water is collected by the French Drain and is piped to the sump basin. Then Sump Pump lifts the water up and can send it to the street or storm.
Todays pumps are not only extremely powerful but they are also efficient! They can move anywhere from 40 to 100 gallons a minute.
The systems works like this….
French Drain is perforated pipe surrounded by gravel. This collects subsurface water.
Catch Basins placed in low spots collect the immediate surface water runoff.
When it rains, the water pooling in the is first collected by the catch basins, then the as the ground water rises, the French drain collects the water. All this water is piped to the Sump. The sump pump lifts the water and send it out to the street.
We install French Drain with catch basins everyday! They work great. Even when collecting huge amounts of water. Here is a video showing a recent install. The amount of water collected here comes from 8 yards and the system works!

Many homes in the Orlando Metro Area have yards that slope or grade towards the house and because the lowest point of the yard is below the street curb, a Sump Pump is sometimes used to lift the water from the low spot and pump it out to the street. This a fairly common practice but the key is to use a GOOD SUMP PUMP. We use only Zoeller Pumps for this installation.

Zoeller Pump N267
Below is a drawing and photos of a recent install using a Zoeller N267 Sump Pump. The N267 is a 1/2 horsepower pump with a 2″ discharge. The pump is exteremly powerful and can push water 100 plus feet easily. The pump is no little store bought pump. This pump weighs almost 50 lbs and the retail cost is just over 500.00. While it might sound high in cost, we know it will last a lifetiime!
Take a look at the drawing first. You’ll see just how much water we are draining into the sump pump. The garage has a roof area of over 3000 sq feet. The driveway also drains into the sump pit via the catch basins at the side. Even the neighbors yard will drain into the system. All in all, its about 2000 gallons per 1″ rain fall. That is a lot of water!!!

Then click again! –
While we know and Always tell our customers, “You can never beat Mother Nature”, we do try to get as much drainage out of a system as possible. Sure, it will rain so hard some day, that the pump cannot keep up, but it will take it out quickly! This system will keep up with huge rainfalls, and you’ll rest peacefully knowing it was done right!

Digging out the Sump Pit
Remember! Water Runs Down Hill! So it gets deeper as you go. That’s why we have a pump. The lines will be down so deep, that gravity cannot gp to the street. The Pump has to lift the water and then go to the street.

catch basin collects water from lowest point
Next we are showing the (2) catch basins at the side of the drive. The basins are 12×12 inches. That means 12 inches wide and 12 inches deep. The discharge of these basins runs to the sump pit and they are down about 18″ inches deep. Water from the drive way is collected by these basins and empties into the sump pit where the sump pump lifts it up and pumps it to the street.
Notice there are (3) inlet lines coming into the pit. See drawing above. Catch Basins, Downspouts and Neighbors Yard, all come into this pit. Then The Pump Lifts the water up and out to the street.
