GRC (Glassfibre Reinforced Concrete) production demands precise control over slurry and fibre mixing. Small workshops and precast plants in Portugal often struggle with inconsistent output, clogged pumps, and uneven spray patterns. Manual mixing methods waste material and slow down production. Many producers need a compact machine that delivers consistent fibre-to-slurry ratios without constant supervision. YG Machinery’s GRC shotcrete machine solves these problems with PLC-controlled peristaltic and progressive cavity pump systems. The YG-GRC200 and YG-GRC300 models offer slurry outputs from 10 to 20 kg/min and fibre outputs from 500 to 1000 g/min. These GRC machines have gained attention across Portugal’s architectural precast sector. 【WhatsApp/WeChat/Skype/Phone】+86 159 3715 2330

Case Study One: Portugal – GRC Facade Panel Production
Client Background
A precast producer in Portugal manufactures GRC facade panels for commercial building renovation. The company supplies 2,000 square meters of panels annually. Their workshop runs two production lines with four operators per shift.
Client Challenge
The producer used manual mixing and hand spraying methods. Fibre distribution varied between batches, causing visible surface differences in finished panels. Rejection rates reached 12% due to inconsistent thickness. The client needed a GRC shotcrete machine that could maintain steady fibre-to-slurry ratios and reduce material waste.
YG Solution
YG supplied the YG-GRC300 GRC shotcrete machine with 12-20 kg/min slurry output and 600-1000 g/min fibre output. The progressive cavity pump handles dense GRC mixes without clogging. The PLC touchscreen allows operators to store recipe settings for different panel types. The 150 kg hopper supports continuous spraying for 30-40 minutes between refills. The concentric plus facing coat gun delivers uniform coverage on vertical moulds. Check our main product introduction page for full specs: GRC Spray Machine.
Client Feedback and Results
“The YG-GRC300 cut our rejection rate from 12% to under 3% within the first month. The PLC recipes mean we switch between panel designs without manual adjustments. Our operators learned the touchscreen in one day.” The producer confirmed material waste dropped by 20% and daily output increased by 15%. The company plans to add a second GRC machine for their expanding production line.

Case Study Two: Portugal – Architectural GRC Restoration
Client Background
A restoration contractor in Portugal specializes in repairing historic building facades. The company takes on 15-20 GRC restoration projects per year. Each project requires matching original decorative profiles and textures.
Client Challenge
The contractor needed a compact GRC machine for on-site restoration work. Access to historic buildings often limits equipment size. The client required precise control over fibre output to match original GRC density. They also needed a machine that could switch between repair mortar and facing coat applications quickly.
YG Solution
YG recommended the YG-GRC200 GRC shotcrete machine with 10-15 kg/min slurry output and 500-800 g/min fibre output. The 180 kg weight and 1000*600*1200mm dimensions allow transport in a standard van. The peristaltic pump handles small batches without priming issues. The concentric spray gun delivers controlled output for detailed restoration work. The PLC touchscreen stores multiple recipe settings for different restoration specifications.
Client Feedback and Results
“The YG-GRC200 fits through narrow doorways and works in tight spaces. The fibre output control lets us match the original GRC texture on every project. We completed a 200 square meter restoration in 8 days instead of the planned 12.” The contractor confirmed the machine paid for itself within 6 months through reduced material waste and faster project completion.
