SikaGrout 500 Aqua – Underwater Nonshrink Cementitious Grout (50 lb Bag)

SikaGrout 500 Aqua is a high-performance, nonmetallic, nonshrink cementitious grout specifically engineered for underwater and tidal zone applications. This ready-to-use grout is pumpable and offers exceptional flow, strength, and positive expansion for filling voids and cavities in submerged conditions. Designed to displace water effectively when installed via tremie method or pump, SikaGrout 500 Aqua is ideal for structural repairs involving bridge columns, wharf piles, concrete piling, offshore rigs, and slipways. It develops rapid strength, resists wash-out, and provides long-term durability in challenging marine environments.

Frequently Asked Questions:

Is SikaGrout 500 Aqua safe for use in marine environments?
Yes. It is specifically designed for underwater and tidal zone applications and will not corrode embedded steel.

What is the best method for underwater placement?
Sika recommends the tremie method or low-pressure pumping to displace water and ensure proper compaction.

Can this grout be used in patch repairs?
No. It is not intended for unconfined patching or overlay work. It must be placed in confined forms.
