Engineer-led diagnosis before a single drum is opened.
Most failures we are called to fix are specification failures. Our team surveys the substrate, identifies the root cause, and specifies the system — then applies it with our own trained crews and warranties the result.
Engineer-led survey
Every enquiry starts with a substrate and moisture assessment, not a price list.
Own application crews
Supply and application under one contract — no split responsibility on failure.
Documented systems
TDS, SDS and method statements issued before mobilisation.
Workmanship warranty
Written warranty on applied systems, with scheduled inspection visits.
Recent work, referenced and verifiable.
Specified for the building type, not the brochure.

Share area, substrate condition and timeline — our engineers respond within one working day with a recommended system and budget.
Notes from the field.
Why basement waterproofing fails in Dhaka's water table
Negative-side treatment is a repair, not a design. What to specify before the raft is poured.
Epoxy vs PU flooring: choosing by exposure, not by price
Thermal shock, chemical spill and forklift traffic each point to a different system.
When CFRP is the right answer for an overloaded slab
Load-path checks, anchorage detailing and the site conditions that rule it out.
