Concrete problems we treat
Cracks & water ingress
Active and dormant cracks in slabs, decks and walls, sealed by injection and surface systems.
Spalling concrete
Where rusting rebar has cracked and pushed off the concrete cover, we treat the steel and reinstate the surface.
Decks, planters & basements
Trafficable and buried concrete that must hold water out (or in) under load and movement.
Construction-joint leaks
Cold joints and movement joints that weep, sealed with injection and jointing systems.
Concrete repair & waterproofing methods
PU & epoxy injection
Resin injection to seal cracks and voids and re-bond the concrete against water.
Cementitious coating
Cement-based waterproof coatings that bond to concrete for slabs, planters and wet areas.
Crystalline waterproofing
Reactive crystalline systems that grow into the concrete’s pores and self-seal fine cracks.
Spalling & structural repair
Rebar treatment and patch repair to restore spalled concrete before waterproofing over it.
How we work
One clear process, start to warranty
The same disciplined method on every job, so you always know what happens next and why.
- 01
Diagnose
A free, no-obligation site inspection. We trace the water path to its true source, not just where the stain shows, using moisture mapping and, where needed, rope-access close-up survey.
- 02
Recommend
A clear written recommendation matched to your building, budget and timeline: the method, why it suits Singapore’s climate, what it costs, and how long it lasts.
- 03
Execute
Our trained crews carry out the works with minimal disruption, surface preparation, treatment and protective coating done to specification, with safety and tidiness on site.
- 04
Document
You receive a photographic record of the works and, for façade inspections, a full condition report, the documentation facility managers need for BCA and building records.
- 05
Warranty
Every completed project is backed by a Certificate of Warranty, from 1 to 10 years depending on the system, so the result is protected long after we leave.
Common questions
Straight answers to what homeowners and building managers ask us most.
Spalling happens when water and chlorides reach the steel reinforcement inside concrete; the steel rusts, expands and cracks the concrete cover off. It can be repaired: we expose and treat the corroded rebar, reinstate the concrete with a repair mortar, and apply a waterproofing system so it does not recur.
