EPS Cement Sandwich Wall Panel is a high-performance, lightweight energy-saving building material designed for modern construction. It features durable face panels made from fiber-reinforced calcium silicate board or cement calcium silicate, with a core composed of expanded polystyrene (EPS) foam particles and cement, compounded into a solid, integrated panel through an automated manufacturing process.
These panels are widely used as non-load-bearing interior and exterior walls, as well as partition walls, across a diverse range of residential, commercial, and industrial buildings. Common applications include prefabricated houses, single-family homes, apartment complexes, dormitories, luxury villas, industrial warehouses, production workshops, hotel and bar constructions, retail spaces, school buildings, medical facilities, and airport projects.
In this guide, we will provide a step-by-step overview of how to install EPS cement sandwich panels correctly and efficiently. Continue reading to learn best practices and ensure a successful installation. If you have any questions during the process, feel free to reach out—we’re here to help.

Preparation and process for installation of HANMERO EPS WAll PANEL

EPS Cement Sandwich Wall Panels Installation Tools

Key Construction Points

1. According to the design requirements, flexibly deepen the panel layout drawing. Mark the installation position of the partition wall panels and door/window openings on the floor. Panel layout should follow the panel width (including a 5mm joint gap).

2. Panel stacking location: The foundation must be solid, flat, and dry. Panels must not be in direct contact with the ground. Avoid stacking too high, and use dedicated carts for transportation.

I.Installation preparation

1. Construction tools: Forklift trucks, Transfer trucks, Steel tape measure, Small hammers, Mortar buckets, Mud scrapers, Infrared level, Electric saw, Aluminium alloy level ruler(2 metres and above), Crowbar, Panel cutting machine, Mortar board, Wooden wedges, Angles, and so on.



2. Construction accessories: Hanmero Adhesive, Render, U-clips, anti-cracking tape and so on.

II.Installation process

1. Each project, each floor has a different height. A design collage work needs to be done for each wall according to the floor height of the project in order to calculate how to cut the panels. This is usually done by cross-panelling, as shown in the pictures below:

2. According to the construction drawings and panel layout plan, snap control lines on the floor using ink lines. Begin panel installation from the edge of the wall or column, proceeding in sequence. For door openings, install panels symmetrically from the opening to both sides.

3. Clean the wall and floor surfaces, then apply an adhesive mortar bonding layer. Erect the panel upright against the wall or column edge, use a crowbar to push the panel tightly into place, secure with wooden wedges, and adjust verticality and level with a spirit level and laser level.

4.The required dimensions of the wall were calculated from the design collage and the wall panels were cut using a portable cutter.

5.After installing the first panel, proceed with the next one. Align the tongue-and-groove joints, fill the joints with adhesive mortar, and insert a 200mm-long, φ6 rebar diagonally at 45° for fixation. Once verticality and flatness are confirmed, repeat the process.

6.Move the ready-to-install panels to the fitting position and press the wall panels firmly against each other with an iron crowbar. Allow the mortar to extrude through the joints until full. Scrape off excess material to create a smooth joint.

7.Bonding mortar shall be applied to the underside of the slab or beam. The proprietary panels are then installed and temporarily secured using wooden wedges. At the connection between the beam and the panel, fix U-shaped steel brackets using nail guns at a spacing of one bracket every two panels. For connections with the floor and wall, drill holes using an impact drill and insert φ6 U-shaped rebars, creating staggered connections with the top U-shaped brackets.

8.Leave space for door and window openings during installation and anchor them with wall brace or moulding. At L-type and T-type connections, insert diagonal steel bars (≤1000mm apart) for reinforcement.

9. Alignment and fixing. Check vertical and levelling corrections with a level ruler of 2 metres and above.

10.Anti-crack treatment. After the mortar and walls are fully set, the fibreglass fabric is applied at all joints with Hanmero Adhesive mortar.

11. Installation of wires and switches. The location of the concealed wires and switch boxes will be set up with infrared light, and cut slots with a portable electric saw.
