Basement Waterproofing in Ipswich
Basement waterproofing prevents groundwater entering below-ground spaces. We install Type A (barrier tanking) at £100-150/sqm and Type C (cavity membrane systems) at £120-200/sqm. A typical small basement (20 sqm) costs £2,400-4,000 complete. All work meets BS 8102 standards.
Waterproofing Systems
Type A (Barrier): Cementitious tanking applied to walls and floor. Prevents water ingress directly. £100-150/sqm.
Type C (Cavity Membrane): Studded membrane creates a cavity behind plasterboard. Water drains to sump pump. More robust. £120-200/sqm.
Sump pumps: Installed where Type C systems need drainage. £600-1,200 including chamber and pipework.
