What Builders Say About Us
Real site feedback from civil engineers, main contractors, and architects who rely on Solphem.
"Solphem's 4mm torch-on membranes and crystalline slurries performed exceptionally on our commercial basement in Westlands. Not a single trace of dampness even through intense rainy seasons."
Eng. Michael Karanja
Lead Structural Consultant • Apex Engineering Consultants
"Their technical specialists actually visited our site to inspect the slab preparation before the membrane was laid. That level of accountability is rare in Kenya. Highly recommended for flat roofs and podiums."
Arch. Wanjiku Mwangi
Principal Architect • Studio ArchDesign
"Material dispatch to western Kenya was fast and hassle-free. Everything arrived on site within 48 hours with full test certificates. Their advice on joint overlap saved our team valuable installation time."
Benson Omondi
Project General Contractor • Lakefront Builders Ltd
"We buy all our expansion joint sealants, swellable waterstops, and bitumen primers from Solphem. Consistent quality, durable products, and fair commercial rates for contractor teams."
Peter Kipruto
Senior Civil Site Engineer • Rift Valley Infrastructure
"We faced severe saline groundwater infiltration on our coastal site. Solphem supplied heavy-duty HDPE geomembranes and swelling bars that completely sealed the tank structure."
Eng. Daniel Mutua
Senior Civil Contractor • Coastal Marine & Civil Works
"Accurate product estimations and honest pricing. Their team calculated the exact rolls of torch-on membrane and primer needed, with zero wastage on site and quick delivery."
Hellen Chebet
Project Quantity Surveyor • Apex Commercial Developments
