Concrete outperforms wood as a construction material, and won't burden building owners with constant repair and maintenance costs. Versatile, long-lasting and durable, concrete is a cost-effective, sustainable choice for both residential and commercial buildings. When it's built with concrete, it's built to last. Concrete is a building material that gains strength over time. Concrete's 100-year service life conserves resources by reducing the need for reconstruction. Concrete is durable - it resists weathering, erosion and natural disasters, needs few repairs and little maintenance, adding up to a solid investment.
