For jobs that require excess reinforcement, seek out ห้างหุ้นส่วนจำกัดสหคอนกรีตอัดแรง rebar, wire mesh and backer rod to present it the energy needed to withstand factors and impact. The moment it’s all poured with a one among our electrical concrete mixers, think about using concrete stamps to add a little bit added aptitude and Visible fascination.
Concrete has inherent fire-resistant Houses, and when blended with steel reinforcement, reinforced concrete structures can withstand superior temperatures and guard the integrity with the creating through a fireplace.
