Introduction
Roof heat insulation and waterproofing are core parts of building energy conservation. Traditional roof insulation materials like polystyrene boards, rock wool often face aging, hollowing, water seepage and short service life problems. Foam concrete (cellular concrete) constructed by dedicated foam concrete mixing & pumping equipment has gradually become the mainstream solution for roof thermal insulation, slope making, and integrated waterproof insulation projects.
Our integrated foam concrete equipment set includes feeding mixer + high-pressure foam concrete pump (Model FP-J100). It realizes automatic batching, uniform foaming, on-site continuous mixing and long-distance pumping pouring, perfectly adapting to flat roof, sloped roof, large-area factory roof, residential building roof insulation construction.
1. Working Principle of Foam Concrete Roof Insulation Construction
1. Raw material feeding: Cement are lifted into the mixing tank via the screw feeder of the blue vertical mixer;
2. High-speed stirring & stable foaming: The equipment mixes cement slurry evenly, mixes with compressed air and special foaming agent to form uniform closed-cell foam concrete slurry;
3. Pumping & on-site pouring: The FP-J100 foam concrete pumping machine delivers lightweight slurry to the roof construction surface through pipelines;
4. Leveling & curing: Manual leveling, natural curing forms a whole lightweight thermal insulation layer.
The finished foam concrete layer features closed-cell structure, low thermal conductivity, lightweight load reduction, and seamless integral pouring without splicing gaps.
2. Core Advantages of Using Special Foam Concrete Construction Equipment
2.1 Excellent Construction Efficiency, Suitable for Large-area Roof Projects
- Integrated feeding, mixing and pumping, continuous non-stop construction, daily pouring area can reach thousands of square meters;
- Mobile wheeled design, flexible transfer between multiple buildings and roof construction sites, no complicated assembly.
2.2 Perfect Integral Pouring, Avoid Common Roof Insulation Defects
Unlike spliced board insulation materials, foam concrete is poured integrally on the roof base, with no joints, completely solving hidden troubles such as cold bridges, water seepage from gaps, board hollowing and falling off.
2.3 Ultra-light Weight, Greatly Reduce Building Roof Load
Dry density of roof insulation foam concrete ranges from 300~800kg/m³, only 1/3~1/5 of ordinary concrete. It will not cause additional pressure on the roof beam and slab, effectively extending the service life of the original building structure, especially suitable for old building roof renovation, factory steel structure roof reconstruction.
2.4 Dual Effect: Thermal Insulation + Heat Insulation + Waterproof Auxiliary
Closed-cell structure inside foam concrete effectively blocks heat conduction and hot air convection, greatly reducing indoor temperature rise in summer and heat loss in winter; meanwhile, the compact hardened layer has excellent anti-permeability, can assist roof waterproof layer to prevent rainwater infiltration.
2.5 Long Service Life, Low Comprehensive Maintenance Cost
Same material as cement base, strong bonding with the original concrete roof base, no aging, no decay, no insect damage, service life synchronized with the building itself. Compared with organic thermal insulation boards that need rework every 5-10 years, the long-term economic benefit is prominent.
3. Suitable Roof Construction Scenarios for This Equipment
1. New residential building, commercial building flat roof thermal insulation, roof找坡 (slope making) construction;
2. Old community roof renovation, roof leakage treatment + thermal insulation upgrading;
3. Large factory workshop, logistics warehouse, market large-area roof insulation;
4. Steel structure roof, color steel tile roof thermal insulation and anti-condensation construction;
5. Roof garden base lightweight filling, roof recess backfilling.
4. Construction Process Standard with Foam Concrete Equipment
1. Roof base cleaning: Remove dust, debris, loose layers on the roof surface, repair cracks and pits;
2. Equipment layout: Place the main unit, mixer, and feeding machine unit on the ground near the building, and lay pumping pipelines to the roof construction area;
3. Raw material proportioning: Set the proportion of cement, foaming agent and water according to design thermal insulation density;
4. Mxing & foaming: Start the feeding system, automatic stirring to form stable foam slurry;
5. Pipeline pumping pouring: Pour layer by layer according to the designed thickness, control pouring speed to avoid bubble collapse;
6. Surface leveling and maintenance: Smooth the surface in time, cover with moisturizing cloth for 7-day natural curing.
