Mason Formwork Type Floating Floor
 

Mason Formwork Type Floating Floor System basically consists of Low Dynamic Stiffness (LDS) Rubber isolators, plywood panel, polyethylene sheeting, reinforcement, concrete block, and isolation board. The LDS Rubber isolator consists of various sizes with different capacity and deflection. Cement perimeter isolation board which made of PVC foam with asphalt face around all walls, columns, curbs, etc. Floor drain can be installed where necessary.

Installation method: The LDS Rubber isolators are evenly placed on the structural floor. The isolators are then covered by 1/2” (12 mm) thick plywood or corrugated steel sheet followed by a 0.15 mm polyethylene sheeting and reinforcement. The concrete is poured onto the surface prepared as above and wait for curing. Caulk all perimeter isolation board with acoustical caulking made of synthetic rubber.

The concrete slab isolated from and supported above the waterproofed structural slab by resilient LDS Rubber isolators forms an air gap between the floating floor and structural floor acts as isolator which helps to effectively eliminate vibration, sound and impact.


 
 
 
Mason Jack-up Floating Floor
 

Mason Jack-up Floating Floor System basically consists of polyethylene sheeting, LDS Rubber jack-up mounts, reinforcement, concrete block and isolation board. The LDS Rubber jack-up mounts consists of various sizes with different capacity and deflection. The isolator is within the bell shaped cast iron housing. Lifting bushing and stop screw are all encompassed inside the bell shaped cast iron housing which facilitates jack-up motion. Cement perimeter isolation board around all walls, columns, curbs, etc. Floor drain can be installed where necessary.

Installation method: The entire floor area is covered by 0.15 mm polyethylene sheeting. The LDS Rubber jack-up mounts are evenly placed on the structural floor followed by reinforcement. The concrete is poured onto the surface prepared as above and wait for curing. Remove the rubber plugs on the cast iron housing of the jack-up mounts and rotate the adjustment bolt on each jack-up mount strategically.

The concrete slab is isolated from and supported above the waterproofed structural slab by resilient LDS Rubber isolators forms an air gap between the floating floor and structural floor acts as isolator which helps to effectively eliminate vibration, sound and impact.

The Jack-up system outperforms the Formwork system in the following ways:

  • It allows the rolling of heavy equipment into position before the floor is raised so as to prevent the floor from cracking.
  • As there is no plywood between floors, the possibility of fire hazard is eliminated.
  • Short circuiting of air gap by concrete spills between plywood panels is impossible to occur.
 
 
Mason Building Isolation System
 

Noise and vibration isolators are used to prevent the downward positive transmission of vibration from a machine to a structure, the upward negative transfer from the structure to a sensitive machine or to isolate a complete building from ground vibration.  There are different types of isolator for building foundation isolation.  Neoprene and natural rubber pads are designed for frequencies as low as 6 Hz.  The capacity of steel spring assemblies from 19 to 50 mm is 1,000,000 pounds.

Mason’s capabilities include mold manufacturing and steel work in addition to rubber mixing and molding.  All rubber products are molded under tremendous pressure of about 1000 pounds per square inch that comes from the huge hydraulic press cylinders.  Besides, Mason’s steel spring isolators do an excellent job of stopping vibration.  They are manufactured with 50 mm thick isolation pads and can be made to any capacity.  The precompressed spring assembly is available with neoprene friction and isolation pads installed on top and bottom of the holders.  Hydraulically adjusted spring isolators are also available with temporary support provided by concrete piers or individual steel stanchions.

Mason Bridge Bearings Pads
 

Mason Bridge Bearings Pads support bridges or highway overpasses using solid neoprene or natural rubber compounds of high loading per square.  The molded product has high tensile and elongation characteristics and minimal permanent set and creep.  They passed the rigid tests in ozone and oxygen resistance.  Capacities are controlled by area, hardness, thickness and perimeter relative to the loaded area.  Pads can be stacked with 3 mm steel plates between them up to 17.5 kg/cm2 for higher deflections and greater efficiency.  The standard sizes are 10” x 10”, 8” x 8”, 6” x 6” and 4” x 4” while maximum loads are 11340 kg, 7257 kg, 3583 kg and 1089 kg respectively.  The standard thickness is 1” while the deflection is 1/8".  However, custom-made pads are also available to suit specific needs.

 
 

GETZNER SYLOMER Special Polymer Pads

 
 

Getzner Building Vibration Isolation Mats
 

Getzner Sylomer® Building Vibration Isolation Mat is a micro-cellular polyurethane elastomer with excellent mechanical performance and durability.  The material does not lose its elasticity even when it is completely encased.  Depending on the type and thickness of Sylomer®, natural frequency of pad is between 7 to 11 Hz.  Sylomer® is hydrolysis stable and resistant to diluted alkaline, acids, oils and grease that are commonly used during construction.  Besides, it also possesses excellent resistant against Ozone and is itself biological resistance.  The elasticity can be remained even at low temperature.  It is because of the micro-cellular surface, particles of dirt and water damage is impossible.

The structural noise and vibrations from railways in the vicinity of the building, industrial processes or equipment can be reduced by the application of Sylomer®.  The bedding can be installed over the full surface, in strips or at individual bearing points which depends on the specific natural frequency and construction features.  The reinforcement can be fitted directly on the mats.  Concrete can be poured directly onto the mat in most of the cases without using any polythene membrane if close cell type Sylomer® is used.

The standard thickness of Sylomer® is 12 mm, 25 mm and 50 mm, and could be varies as according to customer requirement.

 
 
Getzner Sylodamp
® High Damping Pads
 

Getzner Sylodamp® Pads is micro-cellular polyurethane elastomer created by a foaming process that can be used for a wide variety of industrial applications, provides exceptionally good insulation properties and withstand extreme conditions in many situations.  It is also ideally suited for protecting equipment against wear, for sealing and for friction linings, or as elastic elements in general.  The key advantage of Sylodamp® is its high energy-absorbing and damping properties.  The standard types is available in 1500 x 1500 mm while the thickness in 12, 25 and 50 mm.  It can also be produced to meet customer’s specific needs.

 
 
Getzner Sylodamp® Sleeper Base/ Ballast Mat Isolation Pads
 

Getzner Sylomer® is micro-cellular polyurethane elastomer that can be used for sleeper base/ ballast mat isolation pads.  It is created by a foaming process, which is conducted without environmentally harmful foaming agents and free of any softening agents.  It combines spring and shock absorber to provide exceptionally good insulation properties and withstands extreme conditions in many situations.  It is perfect for reducing loads on the ballast and wheel-track interaction.  Getzner Sylomer® sleeper pads effectively isolate vibration, protect ballast and increase track stability as a whole.  It also helps for the adjustment of track stiffness and reduction of rail corrugation.  The Sylomer® ballast mats significantly reduce static and dynamic forces caused by rail traffic and transfer these forces evenly to the substructure.  It helps to reduce secondary airborne noise, vibrations and wear on the ballast. 

The long lifespan and special features of Sylomer® make it a cost effectively solution to your railway system.
