The answer to 'patio installation has weeds' is that weeds growing through a new patio installation is a common issue. This can happen when the patio base wasn't properly prepared, allowing weeds to push up through the cracks and gaps. Symptoms include unsightly weeds disrupting the smooth surface of the patio and potentially damaging the paving materials over time.
For a DIY patio installation, it's important to take the proper steps to prevent weed growth, such as laying down a weed barrier fabric and using a thick, compacted gravel base. However, if weeds are already present, it's generally best to call in a professional landscaper to properly remove the weeds and address the underlying issues to ensure a long-lasting, weed-free patio.
