Below-Grade Waterproofing

Basements and foundations sit in wet ground under pressure. This system keeps groundwater out of occupied and structural spaces below grade, from excavation to backfill.

How the system works

Positive-side protection is applied to the external face before backfilling, with joint and penetration details resolved first, since below-grade repairs cost many times the original work. Where excavation access no longer exists, internal cementitious systems resist negative-side pressure. Protection layers guard the membrane during backfill.

Common questions

Asked on real sites.

Positive side or negative side, which do I need?

Positive side (the wet face) is always preferred and applied during construction. Negative side systems exist for retrofit where you can only reach the dry face. The product TDS states which pressures each system handles.

Does drainage replace waterproofing?

No. Drainage reduces pressure, waterproofing blocks water. Deep basements in wet ground normally need both.

Can I waterproof an old leaking basement from inside?

Often yes, with negative-side cementitious systems after crack treatment. Send us photos of the leaks on WhatsApp and we will confirm the right sequence.
