ConcretersinGlenelg
Glenelg is beachside Adelaide. Salt exposure affects concrete durability in ways that inland suburbs do not experience. We connect you with concreters who specify the correct mix, sealing, and slip-rated finishes for the marine environment.
Marine concrete in Glenelg
Glenelg's position directly on Gulf St Vincent means airborne salt deposits on concrete surfaces daily. The effect is cumulative: chloride accumulates on and in the concrete surface, eventually reaching the steel mesh reinforcement. When chloride concentrations at the mesh reach a threshold, corrosion begins and the expanding corrosion products spall the surface.
The mitigation is a combination of dense mix (32 MPa) and penetrating sealer (silane or siloxane). Penetrating sealers create a hydrophobic barrier within the concrete rather than on the surface, so they cannot peel or delaminate. Re-application every 5 to 7 years maintains the protection.
Pool surrounds in Glenelg are a specialist application. The combination of chlorine from the pool, salt from the marine environment, and constant wet-dry cycles requires both the correct concrete spec and the correct slip-rated sealer. AS 4586 R11 is the standard for pool surround applications.
