Insulation Service

At Prime Blocks Tech, we take the solution from the blueprint to the construction site. We don't just manufacture the material; we offer complete installation services for these three critical systems: facades (EIFS), radiant floors, and inverted roofs. Our technical team handles the on-site execution, ensuring that every EPS block is placed with the precision needed to guarantee maximum energy performance and the durability your project demands.

Facade Insulation via EIFS System

Facade Insulation via EIFS System (Walls)

In this scenario, Prime Blocks Tech’s high-density rigid EPS blocks are used as the core of the Exterior Insulation and Finish System (EIFS).

The Application:

Rigid EPS panels are attached directly to the exterior wall (brick or concrete) using adhesive and mechanical fasteners. Then, they are coated with a base coat mortar and reinforcing mesh.

The Benefit:

This method eliminates 100% of thermal bridges (temperature leaks through beams and columns). By using our EPS, the building retains heat in winter and stays cool in summer, while also protecting the structure against thermal shock and cracks.

Under-Slab and Radiant Floor Insulation

Under-Slab and Radiant Floor Insulation (Floors)

For modern homes seeking maximum efficiency, the use of rigid EPS under the slab or subfloor is vital.

The Application:

Before pouring the concrete floor, high-compressive strength EPS boards are placed over the structural slab. The radiant heating pipes are then installed directly on top of these boards.

The Benefit:

The EPS acts as an unsurpassed thermal barrier, preventing radiant heat from being lost to the subsoil or the floor below. This ensures that heat energy is directed exclusively upward (into the room), improving heating system efficiency by up to 20%.

Walkable Inverted Flat Roofs

Walkable Inverted Flat Roofs (Buildings)

In the construction of multi-story buildings with flat roofs, rigid EPS is the ideal solution for roof waterproofing and insulation.

The Application:

The "inverted roof" concept is used. The EPS is placed on top of the waterproofing membrane, protecting it from the sun and temperature fluctuations.

The Benefit:

Thanks to the extremely low water absorption and high mechanical strength of Prime Blocks Tech EPS, the rooftop remains perfectly insulated. Furthermore, its rigidity allows for gravel or pavers to be placed on top, making the roof accessible and walkable for tenants without damaging the insulation.

Geofoam for Civil Engineering

Ground Stabilization and Road Infrastructure (Geofoam)

At Prime Blocks Tech, we offer high-density EPS blocks (Geofoam) as an advanced geotechnical solution to solve the most complex challenges in civil engineering. This material redefines earthworks by replacing heavy traditional fill with an ultra-lightweight, engineered, and predictable structure.

Technical Application:

Geofoam is fundamentally used in the construction of road embankments, bridge approach ramps, and lane widening on unstable slopes.

Process:

Large EPS blocks are stacked geometrically directly onto the subsoil (even if soft or compressible).

Integration:

The blocks are locked together using mechanical grippers to form a unified, stable mass. Subsequently, a load distribution slab (concrete) is placed on top, upon which the final road pavement is constructed.

Retaining Walls:

It is also used as backfill behind retaining walls to eliminate the lateral pressure that soil typically exerts on the structure.

Key Benefits

  • Load Reduction (1% of Soil Weight): While traditional soil fill weighs approximately 125 lbs/ft³ (2,000 kg/m³), Prime Blocks Tech Geofoam weighs between 1-2.5 lbs/ft³. This virtually eliminates long-term settlement and sinking, protecting the integrity of the road and underground utilities.
  • Accelerated Execution: Installation is extremely fast and requires no heavy compaction machinery or constant soil density testing. Furthermore, installation does not stop due to rain or adverse weather, reducing construction timelines by up to 50%.
  • Structural Savings: By reducing the load, engineers can design thinner retaining walls and shallower foundations, translating into direct savings on concrete and steel.
