Marine environments can pose significant challenges to construction, repair and maintenance of buildings, structures and civil engineering works.
Significant issues to take in to account include:
Aquatic Mortar Accelerated - a very fast setting anti-washout mortar design for use in wet and/or underwater conditions. It achieves high early strength gain even in low temperatures and will not break-up or disperse when applied underwater. Suitable for repairing concrete sea defences, marine structures, harbours, jetties, tunnels, pipes, sewers, docks, culverts, bridges, locks etc.
Aquaplug - a rapid setting mortar designed to plug leaks in building structures and to seal joints to prevent the inflow of water.
Febtank Plug - ultra rapid setting waterstop repair compound that can be used to plug live water leaks in masonry and concrete structures, it can be used above and below water. Suitable for plugging holes, cracks and joints. Forms a water-tight seal.
Spraydeck Rapid - an ultra fast setting anti-washout dry spray applied shrinkage compensated concrete. Achieves high early strength gain and is thixotropic, allowing high-build. It can resist water ingress between piles and ground founded units. Suitable for moving water situations, culverts, tunnels, marine defences and rapid strength barriers.
Marine Mortar - a fast-setting anti-wash out gun applied mortar, specifically designed for application that can only be carried out between tides / at low tide.
Acropak HB40 Mortar - a lightweight cementitious repair mortar suitable for use in harsh marine environments.
Nitomortar UA - a two-part epoxy resin mortar suitable for use in very wet and or underwater situations. It is highly durable and resistant to physical damage, has excellent bonding and adhesion, high strength and excellent chemical resistance. It can be used on both concrete and steel. It is ideal for repairing structures that withstand a heavy battering from the sea, such as piers, jetties, submerged structures etc.
Febset 45 - a fast-setting rapid strengthening repair motar that can be used for repairs on quays, roads and bridge decks, even at sub-zero temperatures. Enables very short shut-down periods to carryout work and can be trafficked after minimal time periods (time varies depending upon the ambient temperature during application, see link for more details).
Conbextra UW - an anti-wash out cementitious shrinkage compensated grout for use underwater and within tidal zones. Suitable for quay pillars, slipways, bridge columns, stanchion plates etc.
Lokfix - a range of epoxy resin anchor grouts that can be used underwater. Used for anchoring / fixing steel bars in to rock, concrete, brickwork and masonry.
100 Newton Grout AW - an ultra high strength shrinkage compensated grout designed for use in the wind turbine industry. AW denotes that it is an anti-washout grade, there is also a standard grade. It can support the heaviest of structures, including crane rails, bridge bearing seats, ground anchors and baseplates for machinery or structures; as well as offshore structure repairs, wind turbines and underwater grouting applications.
CSW Grout - a water resistant grout designed for use in wet conditions such as sea defences, marine structures, harbours, jetties, tunnels, docks, locks, culverts, bridges, pipes, sewers etc. It is resistant to sea water, oils and mild alkalis.
CSU Grout - similar to the CSW grout in performance but this grade is specifically for underwater applications.
Cebex 250 - an anti-wash out admixture for grouts to be applied underwater. The admixture forms a gel around the around cementitious grout particles.
Nitomortar UA - a two-part epoxy resin mortar that can be used underwater and in exceptionally wet conditions. It can be used to repair steelwork and concrete on submerged marine structures such as jetties, piers, sea walls etc.

SikaSwell A are swellable hydrophilic acrylic waterstop/waterbar strips that can be used to seal and prevent water ingress through construction joints and penetrations through concrete. They can be used for both salt water and potable water ingress situations. For more information see Waterbars & Waterstops page for more information.
Grouts suitable to carry high dynamic loading and vibrations typically required for grouting crane rails include: E33, E70, Epicon L Grout, Epicon M Grout, Epicon RT Grout, Nu Grout Superflow, Nu Grout Hi Spec, 100N Grout, Masterflow 765, Masterflow 885, Masterflow 101, High Build Mortar, Febset 45, Conbextra EP and E140.
Chemcure S is a saline compatible concrete curing compound. It acts to greatly reduce hairline cracks and crazing associated with shrinkage on both horizontal and vertical concrete surfaces during the curing process.
