 Waterproofing foundations
is all about barriers and volume. If your foundation walls have a great enough barrier to stop the volume of water, then a barrier is in place and the ground water rises and creates run off completing the water table cycle.

 If your foundation walls have holes and cracks the barrier is void and then water infiltrates. Old, deteriorated lime joints lose their waterproofing ability over time by ground water wicking through the foundation walls from hydrostatic pressure and capillary action. This water cycle process of ground water and salts deteriorates the foundation base joints and causes seepage and/or loose flaky joints.      
 Removing these soft lime joints and re-pointing with portland cement based mortars restores the necessary barrier to prevent leaks and water infiltration.

 If the volume of outside water is too great it can be differed by drains and down spout extensions. Interior elevation issues can be addressed with interior perimeter drains and sump pumps.
 We very rarely have to rely on perimeter drains, excavators or sump pumps
 Almost all foundation waterproofing can be completed by thorough wall repairs, water diversion and waterproofing coatings.

This Massachusetts basement sealing or basement waterproofing process includes addressing all structural foundation repairs first.

Structural foundation repairs range from setting loose stones and bricks to foundation wall partial rebuilds. If your basement and foundation walls are straight (plumb) then we move on to a thorough inspection of voids and loose masonry, foundation cracks and deteriorated wall joints or plaster coatings.

 Filling all masonry voids and removal of the aged lime (soft, flaky, white masonry) joints and then repairing foundation walls with stone and brick pointing is a must in true basement sealing or waterproofing foundations. Only after the foundation is completely repaired (all voids filled, all holes plugged, all water infiltration stopped, all masonry joints repaired, all bricks repaired, all loose masonry set) then do we move on to waterproofing wall coatings.
We use several different fortified cement based products and elastomeric paints to treat basement walls depending on waterproofing requirements and customer request.

  Simply attempting to coat walls with sealants without masonry repairs is a futile effort often resulting in very poor results at great cost. Magic sprays and mixtures are no match for traditional masonry coatings and repairs. We repair foundations and waterproof basements the old fashioned way, by hand.  We chisel out all failing masonry joints repairing them creating a full repair of your basement and foundation walls.
