Commercial Land Remediation & Environmental Services Zirkon

Zirkon, the commercial arm of TP Knotweed Solutions, provides a full range of environmental and land remediation services managed through one trusted supplier. From invasive plant surveys and ecology to vegetation clearance and full remediation, we work with construction companies, property developers, local authorities, and land managers across the UK, clearing the obstacles that stand between you and groundworks.

One Trusted Supplier for All of Your Land & Remediation Requirements
Managing separate contractors for surveys, ecology, clearance, and remediation introduces coordination risk, gaps in accountability, and additional cost. Zirkon brings the full scope of commercial land services under a single supplier, so your programme is managed by one team from the first site survey through to completion of works on the ground. We have assisted with large-scale construction and regeneration projects across the UK, with extensive experience across a wide range of industries and sectors. Whatever your site requires, we will have worked with someone in your business area before.

Our CSJK-qualified surveyors identify and GIS map all Schedule 9 species present, assess the extent of any infestation, and produce a full written report with a recommended remediation strategy.

Get Ahead of the Risk
Environmental constraints discovered after groundworks have started, or after contracts have exchanged, can halt a development programme, trigger unbudgeted costs, create planning complications, and lead to significant additional spread or disturbance on site. Commissioning a survey at the earliest stage of a scheme gives you an accurate picture of what is on site, what it will cost to address, and how it should be programmed. That information protects your budget, your programme, and your planning position.
