Water coming up from the Floor- wet basement-How to repair a wet basement
Hydraulic pressure* is a common problem, that is a result of a collapsed or plugged weeping tile or no weeping tile or sump pump installed at all. This will prevent water from being taken away from under the house. To repair this problem of a wet basement – a new weeping tile or o-pipe-perforated is installed either inside or outside often in conjunction with a sump pump-sometimes called a french drain. Our most common weeping tile installation is an interior repair called a French drain.
The floor is broken up along the leaking walls and a trench is excavated. A Four-inch perforated weeping tile is placed in the trench and covered with clean gravel to help with drainage. All excavated materials are removed from the site.
A Delta or Platon waterproof membrane is installed to cover the wall and travels under the floor connecting with the weeping tile. The drainage system is routed to a sump pump which carries the water away from the house. New concrete is poured to repair the floor. The same results can be achieved from outside but the cost is considerably higher and not usually our first recommendation.
*Hydraulic pressure is water pressure forcing water up through the basement floor due to outside drainage water pressure coming down the outsides of your foundation wall-this downward pressure of draining surface water from e.g. spring rain falls or winter thaws -this forces water up through the floor-the opposing pressures try equal out.
If we have to repair from the outside or exterior-this type of repair requires excavating along the outside of the leaking wall or structure exposing the wall from the top down to the footing. After the wall has been cleaned and repaired, a waterproof membrane is installed to cover the entire wall. This system will prevent water from being in contact with the wall and will solve the problem permanently. A short slideshow on an exterior membrane install-repair.
Block Wall Foundations -wet basement issues-
Construction block foundations have mortar around every block making hundreds of joints which can lead to leaking. Construction blocks are hollow which means they can fill with water. For these reasons, if you have a finished basement, or planning to build a finished basement, we recommend you always repair it. There are only two repairs available to fix this problem. You can do an exterior repair or an interior, both repairs are good but we usually recommend a French drain that is installed from the inside.
The French drain is a much less expensive repair then outside system. You are guaranteed to solve two problems simultaneously. This system will deal with water coming through the wall and up from under the floor. With the more expensive exterior repair, you are often only successful in waterproofing the wall but not able to improve the drainage. Reason for this is because the weeping tiles around the rest of the house might be plugged, damaged or nonexistent and you would still not be able to control the water from under the floor. With the French drain, we are actually creating a new drainage system inside and under the floor. This will control the water coming through the wall. We have never had a problem with this repair.
What we do is chip up the floor along the leaking wall. We dig a trench and install a modern 4-inch perforated weeping tile and cover it with gravel. Holes are drilled in the bottom course of block to allow the water to drain out. A waterproof membrane is installed over the trench and up the wall as water diversion system. The weeping tile is routed into a sump pump. If there is not an existing sump pump we will supply, install and plumb one for you. We warranty this for life (excluding the sump pump-its warranty is usually 1-3 yrs).
Water entry leaks at foundation wall cracks– Polyurethane foam sealant is used for foundation crack repair-repairs to stop water entry.*
(You also need to find and correct outside water sources e.g. Grading your land so water runs away).
*Cracks in poured concrete walls that are larger than 1/4″, cracks which are increasing in size, or cracks which are otherwise indicative of foundation movement should be evaluated by a professional.Before repairing a foundation crack it is important to diagnose the cause of the crack and its effects on the building structure. The significance of any foundation crack depends on the crack’s cause, size, shape, pattern, location, foundation materials, the extent of cracking, the impact of the crack on the building, and possibly other factors as well. If there is an underlying ongoing problem causing foundation movement or damage, that problem needs to be corrected too.
