Why Basements Leaks

Basements leak because water enters through some sort of penetration. Some of the most common of these include:

  • Foundation cracks;
  • Tie ride holes;
  • Leaking penetrations (e.g., around pipes for electrical, gas, and plumbing);
  • Sill plates;
  • Failed weeping tile;
  • Window wells;
  • Leaking mortar joints; and
  • Construction joints.

Additionally, if a property’s weeping tile drainage system isn’t working properly, water can come up from under the floor, as well as around the edges of the walls. Malfunctioning sump pumps can also cause water to come up through floor cracks.

How Basement Waterproofing Works

Fortunately for homeowners with leaky foundations, it is possible to fix a wet basement from either outside or inside. To repair from the inside avoids the need to dig outside.

To waterproof a basement from the exterior of the home, the earth around the bottom of the foundation wall is excavated. At this point, the weeping tile is exposed; afterwards, it can be inspected and, if necessary, replaced. The walls are then pressure-washed, and all holes and cracks are repaired. New gravel is placed over the new weeping tile. At this point, two waterproof membranes – one rubber, and one air gap – will be installed over the entire subterranean portion of the foundation. The excavation is backfilled and the earth is compacted.

Interior waterproofing is performed by creating a trench through the floor at the floor wall joint along the edge of the leaking wall or walls. The subfloor drainage system or French drain is installed in the trench and covered with clear drainage gravel. An Interior waterproof membrane is installed to cover the foundation walls, and this membrane connects to the drainage system under the floor. New concrete is poured to repair the floor and the system is often connected to a sump pump. This is considered a permanent waterproofing solution and basement finishing can proceed as per usual.

Smaller repairs, like foundation cracks, often require only the injection of high-pressure urethane resin from either inside or outside.

HELPFUL TIP: If the leaking foundation is made up of construction blocks or cinder blocks, it will naturally be expected to leak due to the hollow nature of the foundation walls, unless it has been made waterproof.
