FoundOceanLow Strength Grout
Low strength grouts are typically used for underbase grouting where the void between the base of the structure and the seabed requires filling to ensure an even load distribution over its entire structure.. This grout is clay-like in consistency and the low cement content means that large volumes can be mixed using much smaller cement quantities than standard strenth grouts.
