LSM Spring Lift Slab Floor Mount is a heavy-duty floor isolation solution designed for concrete slabs exposed to significant vibration and impact. Ideal for fitness spaces, basketball courts, generator rooms, bowling centers, and specialist acoustic projects across the UAE, GCC, Middle East, and MENA region, LSM helps control structure-borne noise where impact activity is a key concern.
Engineered for Performance.
Spring-Isolated Slab System for Impact and Vibration Control
LSM Spring Lift Slab Floor Mount is a spring isolator assembly designed to isolate concrete slabs exposed to high levels of vibration, shock, and impact activity. It is a practical solution for spaces where impact-generated noise and structure-borne vibration are more problematic than airborne noise transmission, such as fitness areas, sports facilities, generator rooms, and bowling centers.
Designed for Concrete Slab Isolation
The LSM system uses spring lift slab floor mounts to support isolated concrete slab assemblies. By separating the slab from the surrounding structure, the system helps reduce vibration transfer into adjacent rooms, occupied areas, and sensitive building zones. This makes LSM suitable for consultant-led acoustic and vibration isolation design in commercial, hospitality, sports, entertainment, industrial, and mixed-use developments.
Flexible, Made-to-Spec Isolation Design
LSM fabricated housings are made to suit specific project requirements, allowing flexible isolation system design for a range of slab thicknesses, air cavities, and applied loads. The required deflection and corresponding natural frequency can be determined using one-inch or two-inch rated coil springs, with acoustical design support available to assist in selecting the appropriate configuration for each project.
Reliable Solution for Demanding Building Applications
For acoustic consultants, structural engineers, MEP contractors, and project developers in the UAE, GCC, and wider MENA region, LSM provides an effective approach to isolating impact-prone concrete floor slabs. It supports improved acoustic comfort, better vibration control, and reduced disturbance to surrounding areas in buildings where active use, heavy equipment, or repetitive impact loads are present.
RESILIENT INTERFACE
Adhere resilient interface (PPI by KNC) to all penetrations and perimeters. PPI prevents sound vibration from transferring from the isolated slab to the non-isolated structure.
BOND BREAKER
Cover entire floor with bond breaker (Poly Sheeting by KNC). This ensures that the isolated slab can be lifted into place.
POSITION CANISTERS
Place Canisters with Wooden Lid per engineered shop drawings (by KNC or KNC Representative). Caulk or tape to bond breaker, preventing concrete from leaking beneath Canister.
CONCRETE REINFORCEMENT
Install concrete reinforcement per project drawing and design specifications.
POUR CONCRETE
Pour concrete and allow to cure. Remove and discard wooden lid and screws.
ASSEMBLE ISOLATORS
Grease Lifting and Leveling Screws. Place Spring Assembly into cavity per engineered shop drawings. Balance Steel Lid on Leveling Screw, insert and engage (do not tighten) Lifting Screws.
DRIVE LIFTING SCREWS
Drive Lifting Screws two or three turns for each isolator in sequence until floor is raised. Trim perimeter bond breaker and remove PPI tear strip. Apply sealant in gap.
Fabricated, made-to-spec housings permit flexible isolation system design for a range of slab thicknesses, air cavities, and applied loads. Your acoustical design team can assist you with your specific requirements.
Required deflection and corresponding natural frequency for the floor isolators can be determined using one inch (1″) or two inch (2”) rated coil springs. Ask us about options for the airspace between the isolated (lifted) slab and the structural slab.
Factory-prepared shop drawings detail spacing, spring load/deflections, and structural floor flatness requirements. Our Project Coordinators and Professional Engineers are ready to assist you with your specific design questions.
Rubber cap assembly protects spring coils against resonant or “ringing” frequencies.
Based on your floor system requirements, in-slab or perimeter seismic restraint elements as well as Coulomb Dampers and other damping components are easily designed.
LSM can ship in ready-to-install sub-assemblies. For instance, canister assemblies and related accessories can ship ahead of the spring assemblies based on pour schedule requirements. Spring assemblies can follow once the slab is cured to strength and ready to be raised helping eliminate “missing parts” just when you are ready to lift.
