Basement and concrete slab waterproofing protects your building from ground moisture, rising damp, and structural water damage. At J & G Waterproofing Leaking Specialist Services, we provide professional basement and slab waterproofing in Terengganu with reliable, long-term protection for residential, commercial, and industrial properties.
We don’t just treat surface symptoms — we identify the root cause of water intrusion and solve it permanently.
