RASCOflex PU Polyurethanes – the traditional injection solution
RASCOflex Polyurethane grouts can be split into three categories: standard PU foams, ductile two-component systems and rigid elastic two-component systems. While contact with water is key in initiating the foaming action of the PU foams – which are mainly used as a temporary water barrier – the actual polymerization process of the two-component systems and formation of a compact, durable grout body is triggered by the contact between the two components. The RASCOflex PU500 series features all types of PU foam, e.g. soft, hard, fine-pored, very heavily foaming products. As the premium product in the polyurethane range, the permanently elastic, low-viscosity RASCOflex PU110X is also frequently used in preventive waterproofing for grouting injection channels and hoses. By virtue of its modular system of additives, the rigid elastic RASCOflex PU309 series acts as a multi-purpose solution for a wide range of remedial waterproofing applications. RASCOflex PU112 is the product of choice for structural (force-transmitting) waterproofing injections.

Use
RASCOflex PU118X LM is used for the dynamic waterproofing / bonding of cracks, joints and voids in various areas of construction. The product‘s reaction and properties can be modified as required during injection. For dry and water applications. The product is ideal for ground injection systems, but also for RASCOtec injection channels or other injection hose systems.
RASCOflex PU309L
RASCOflex PU309L is a slow-reacting polyurethane injection resin for waterproofing and consolidation of dry to water-bearing soft ground, rock, concrete and masonry etc.
Use
Its long gel times, controlled viscosity and reaction behaviour upon contact with water make it ideal for waterproofing in case of low water flow speeds, both above water and underwater. Applications include consolidation and waterproofing of porous concrete, masonry, rock and soft ground as well as structural, waterproof filling of cracks, joints and voids.

RASCOflex PU309N
RASCOflex PU309N is a fast-reacting polyurethane injection resin for waterproofing and consolidation of dry to water-bearing soft ground, rock, concrete and masonry etc.
Use
Its short gel times, high viscosity and reaction behaviour upon contact with water make it ideal for waterproofing against hydrostatic pressure in case of low to medium water flow speeds, both above water and underwater. Applications include combating water ingress into excavations, tunnels, drains, sewers, canals and hydraulic structures as well as structural, waterproof filling of cracks, joints and voids.

RASCOflex PU309F
RASCOflex PU309F is a solvent-free, very highly reactive, fast reacting and strongly foaming 2-component polyurethane injection resin. Foaming takes place independently of contact with water. The final foam body is viscoplastic and form-stable.
Use
RASCOflex PU309F is a polyurethane injection resin for waterproofing and consolidation of dry to water-bearing soft ground, rock, concrete and masonry etc. Its short gel time, high viscosity and foaming reaction behaviour make it ideal for waterproofing against hydrostatic pressure under the most difficult conditions. Applications include sealing against water ingress into excavations, tunnels and hydraulic structures.

RASCOflex PU309S
RASCOflex PU309S is a very fast-reacting polyurethane injection resin for waterproofing and consolidation of dry to water-bearing soft ground, rock, concrete and masonry etc.
Use
Its extremely short gel time, high viscosity and reaction behaviour upon contact with water make it ideal for waterproofing against hydrostatic pressure in case of low to high water flow speeds under the most difficult above-water and underwater conditions. Applications include sealing against water ingress into excavations, tunnels and hydraulic structures.

RASCOflex PU309S+
RASCOflex PU309S+ is a solvent-free, very highly reactive, very fast-reacting 2-component polyurethane injection resin. The material foams easily in contact with water.
Use
RASCOflex PU309S+ is a PUR injection resin for waterproofing and consolidation of dry to water-bearing cracks or defects in loose rock, concrete, masonry etc. Due to its very fast reaction time it is very well suited for waterproofing under the most difficult conditions. Fields of application are quick stopping of water ingress in construction pits, basements and hydraulic structures, even at low temperatures.

RASCOflex PU512F
RASCOflex PU512F is a polyurethane-based, 1-component injection
grout which foams upon contact with water. It is primarily used to

or grouting behind diaphragm, contiguous pile or sheet pile
walling.
