BASEMENT EXCAVATION & WATERPROOFING (INSULATION) BASEMENT LEAKS REPAIRS
Waterproofing is a treatment of the surface or structure (building) to prevent the passage of water through the basement envelope under hydrostatic pressures.

Sometimes it is necessary to resort to the extreme measure of exposing the basement walls, treating them to make them watertight, and then re-grading the soil.

The conventional system of waterproofing involves membranes. This relies on the application of one or more layers of membrane that act as a barrier between the water and the building structure, preventing the passage of water.

New technology in waterproof membranes relies on polymer based materials that are extremely adhesive to create a seamless barrier around the outside of a structure.

PARGING (FOUNDATION COATING):
This work should be done only in dry, mild weather. Parge coat (concrete) it is a thin coat of a cementitious or polymeric mortar applied to concrete for refinement of the surface. The newly cemented walls should be properly protected and cured. Freezing or rapid drying of the concrete by sun or wind can damage it and make it worthless. In very wet soils, the parged wall surfaces may be given two coats of hot coal tar pitch.

The intent is to create a contiguous surface by filling surface air voids and bugholes (eliminating Bughole-induced outgassing and to level concrete with extreme rugosity to a level suitable for top-coating with a high-performance protective coating

DRAINAGE ("FRENCH DRAIN"):
A "French drain", perimeter drain or land drain is ditch covered with gravel or rock that redirects surface and ground water away from an area. A "French drain" can have hollow pipes along the bottom to quickly vent water that seeps down through the upper gravel or rock. "French drains" are common drainage systems, primarily used to prevent ground and surface water from penetrating or damaging building foundations.

SUMP PUMP INSTALLATION:
Where gravity drainage is impossible or impaired, a sump pump may be used to raise the water to a level where it can be carried out through a drain line.

A sump pump is a pump used to remove water that has accumulated in water collecting sump pit, commonly found in the basement of homes. The water may enter via the perimeter drains of a basement waterproofing system, funnelling into the pit or because of rain or natural ground water, if the basement is below the water table level - depression. (In geology is a landform sunken or depressed below the surrounding area).

Sump pumps are used where basement flooding happens regularly and to ameliorate dampness where the water table is above the foundation of a home. Sump pumps send water away from a house to any place where it is no longer problematic, such as a municipal storm drain or a dry well.
