Grouting Plants – SEALCRETE

Sealcrete for Tunneling

Sealcrete is a containerized grout plant featuring the Vortimix high-shear colloidal mixer, Simem SuperWash high-pressure mixer cleaning system, on-board agitation tank, and touchscreen automation package. These self-contained units are purposely designed for easy transport, routine installation, and high-output capacity for various applications. When paired with a Simem configured pumping system, external liquid storage tanks, foam generating unit, and powder silos, the SealCrete capability impresses.
SealCrete plants are versatile. Most popularly used to produce bi-component grouts and hydrated bentonite mixes for the infrastructure and heavy construction tunnelling sector, the plant’s ability to produce light-weight cellular concrete (LDCC) and a variety of cement slurry has further advanced SealCrete utilization in the underground mine backfill sector and construction sector worldwide

Auxiliary Equipment

SealCrete plants combine a wide range of auxiliary equipment to satisfy a demand for the scalable production of various cemented mixes. A tailored configuration of standard equipment brings production versatility and convenience to reality. Base unit SealCrete capacity is expandable with bolt-on boost modules which doubles output without expanding plant footprint

Low-Density Cellular Concrete Mobile Grout Plant

Lightweight cellular concrete (LDCC) is ideal for projects requiring a robust and non-structural material to fill a continuous void or area by pump or bulk delivery. LDCC is a lightweight and highly flowable mix of cement, water, and preformed foam. SealCrete for LDCC is equipped with an Automatic Foaming Generator (AFG) and includes digital flow meters for the accurate measurement of liquid and air components. SealCrete automation with a +99% dosing accuracy supportsreal-time foam ratio adjustment to uphold specification for when pumping long distances, at variable elevations, in confined and/or high-traffic areas is required.

Vortimix Colloidal Mixer

VORTIMIX can rapidly mix cementitious grouts as low as 0.6:1 water:cement ratio (by weight). Combined with the optional paddle mixer VORTIMIX can handle grouts as low as 0.45:1 w:c ratio. Ratios can even be lower with the addition of super-plasticizers.

Pumping Systems

Pumping system design must consider many factors prior to operation. Matching a pumping solution for a specific project application requires extensive knowledge to ensure a pumping system performs as intended. Simem Underground designs and assembles complete systems guaranteed to perform. System types incorporate piston, peristaltic, progressive cavity, centrifugal, and air-diaphragm pumps. System come complete with associated power control units, instrumentation, and pipe cleaning assemblies. Systems are prepared for field connection as independent components, skid-mounted, or fully containerized.
