The joints in paving are generally filled with sand, which allow the surface to drain

over the whole area rather than just in channels and drains.

This drainage is compromised when organic matter contaminates the infill material.

This not only restricts the drainage capacity of the surface but also retains

moisture in the filling material. This prolonged moisture

retention and organic material provides ideal conditions for moss and algae to

flourish. This can result in dangerous slippery conditions and produce an

unpleasant odour. In extreme cases the algae can cause puddles leaving a thick

black sticky residue that can solidify when the surface does eventually dry out.

Because the gap between the block allows for it, in many cases other weeds,

may appear and cause further damage to the surface rendering it unusable and

even dangerous.

Using the Kersten range of sweeping equipment and WeedBrushes can effectively

control this situation and maintain the surface in the intended condition.

Kersten provide no obligation demonstrations to potential customers with qualified applications.

Kersten are looking for hire partners and contractors across the UK to hire out the products or provide

the service to customers.

Why this Garden Works

Each article is presented by landscape designer, Tracy Rich, who will examine a single garden and provide design tips based on that garden's layout, materials and planting.

Tuinen Mien Ruys

Mien Ruys' own garden in the Netherlands is the ideal place to start a new series on design articles on 'Why this Garden Works'.

Lan Su Chinese Garden

Lan Su is a great example of urban garden design. Its whole purpose is to help people relax and to inspire creativity by connecting with nature, even in the centre of town. 

Hauser & Wirth Garden

The main wow factor of this garden is the large perennial meadow out the back called Oudolf Field after its famous Dutch designer, Piet Oudolf. However, the gallery complex also contains some other very interesting spaces.
