How expensive are pavers versus flagstone?
Generally, Flagstone material is more expensive that paver stones.
*Pavers typically cost around $4 to $6 (plus labor and installation).
*Flagstone typically costs around $5 to $9 (plus labor and installation) and depending on the type of Flagstone, the thickness, and the shape/cut of the stone (square, rectangle, irregular, or random).
How expensive are permeable pavers compared to non-permeable pavers?
Permeable pavers do cost a little more per square foot than non-permeable pavers.
*Permeable pavers cost approximately $5 to $7 a square foot (plus labor and installation) depending on the style of pavers. The main difference between permeable and non-permeable structures is that this process uses more materials and more soil has to be removed from the area to allow for the drainage stone depth of about 18-22".
*Non-permeable pavers typically cost around $4 to $8 (plus labor and installation).
When it rains, water gets into the basement in Howard County. What kind of drainage solution should be installed?
In addition to the application of other drainage solutions, like drain pipes or swales, there is the option of a more permanent (and more expensive) solution called waterproofing. this means that existing soil is dug away from the foundation of the home, installing a waterproof membrane to the foundation, then installing drainage stone and pipes to exit at daylight. This means that the water will exit the pipe and spill out onto the lawn. The waterproof membranes are adhered directly to the foundation so that the chance of water draining into the basement from outside sources is guaranteed to not happen again.
What are permeable pavers and the benefits of using them over non-permeable materials?
Permeable pavers are a type of hardscape material that allows water to flow in between and around the joints of the pavers, unlike non-permeable surfaces where water can pool and collect. Non permeable paver areas have to be sloped away from the house so water doesn't flow toward the house or pool on the surface. Permeable pavers are used for paving vehicle and pedestrian pathways that allows for rainwater to pass through the material and percolate back into the ground. The material used for the base of permeable paving may be porous to allow for fluids to flow through it or nonporous media that are spaced so that water may flow in between the paver's joints. In addition to reducing surface runoff, permeable paving can trap suspended solids therefore filtering pollutants from storm water.
What kind of materials can be used for hardscape work?
There are several types of materials that can be used for hardsccape work like patios and retaining walls, including including, but not limited to: interlocking concrete pavers, bricks, flagstone, poured concrete, permeable pavers, or natural stone.
