Algae is a plant-like, photosynthetic organism that flourishes in any environment with moisture. Preferring damp conditions, algae is usually indicative of a larger problem going on. Although it usually manifests as patches of green, algae can also be red, brown and even blue.

While it may seem harmless on the surface, if left, it can actually go on to cause a lot of damage, especially to natural stone. The density of algae can suddenly increase with changes to the levels of sunlight or mineral availability.

Large patches of algae on pavements not only act as a slip hazard, but also decreases the traction of the material it’s growing on, further increasing the risks of slips. This is particularly risky in high footfall areas, especially on public footpaths.

While algae is unsightly, it can be far more damaging than you could imagine. Like lichen, algae releases acidic secretions which can go on to cause damage to natural stone, in particular, soft stone such as limestone. It’s also known to collect water and dirt, allowing for the potential to affect the stone’s transpiration rate (water movement), which could lead to issues with damp.

With the use of industry-leading technology, we’re able to effectively and efficiently remove algae from all types of brick, stone or surface without risk of damage to the substrate. Accredited by Stonehealth, we have vast knowledge and experience in returning stone and brickwork to “as new” conditions.

    DOFFSteam Cleaning

    Using high-temperature but low-pressure makes the DOFF system by Stonehealth perfect for carrying out cleans to delicate building materials such as render, natural stone and masonry.

    Its low water volumes (3 - 5 litres per minute) means that deep penetration and saturation of the surface is avoided; the materials usually dry out within a matter of minutes. And because of this, it means that the DOFF can even be used internally, with careful planning.

    Environmentally friendly, the DOFF system does not require chemicals. Impressive results are achieved with water and steam alone. This mitigates the risk of potential chemical reactions with the substrate and means that it's safe to use within the vicinity of pre-established ecosystems.

    The DOFF system is hugely versatile. The operator can fully adjust the temperature and pressure, allowing for the perfect combination for each individual scenario.

    TORCAbbrasive Cleaning

    TORC uses a combination of water, an inert granular stone, and a variety of different sized vortex-creating nozzles to complement the size of the area being cleaned.

    Especially effective on stone and brick, the TORC easily breaks down algae with a combination of swirling, pressurised water containing a substance known as granulate.

    The swirling vortex is created using a mix of low air pressure, a low volume of water and a safe inert fine granulate.

    Because water volume is kept to a maximum of 60 litres per hour, the risk of impact damage is avoided. The TORC system is not a blasting system; it benefits from sensitive controls which means that the operator has full control.

    The TORC system produces results that are probably the most sensitive and efficient for cleaning masonry.
