Wow the first 5 years of business have flown by! It has been a wonderful journey and we are so proud of how our company has grown, with your support.

You are a big part of our journey!

We have achieved so much from small yes moments to great big WOW moments.

Here are just a few of our highlighted achievements along the way:

  • We are coming up to 1,000+ projects completed.
  • We have aided in the creation of over 20,000 dwellings / residential units.
  • We have helped 250+ different clients of all sizes and technical backgrounds.
  • We obtained Constructionline accreditation in April 2020.
  • We obtained ISO 9001 status in June 2021.
  • We are able to offer clients £5m PI (up from 100k when we started!)

We have helped build homes, not just houses; we have helped make many dreams, not just projects come to life and for this we are grateful.

We love what we do and have so many more goals we have set ourselves. We would like to thank you – our loyal clients – for your continued support.

We look forward to the next leg of our journey together with you!

We are pleased to announce that we now offer in-house:


These services complement our core civil engineering offerings of planning, highway and drainage engineering.

We carry out these tests to support surface and foul water drainage design in full accordance with underlying requirements and specifications, ensuring rates are fully accepted by approval authorities first time round and ensuring drainage infrastructure is sized correctly.

Our service includes trial pit data sheet/s identifying strata and thickness encountered, photographs of testing, technical note identifying calculated infiltration rate and recommendations on surface water disposal based on infiltration rates identified.

All our BRE 365 infiltration and BS 6297 Percolation testing reports are fully reviewed and signed off by a chartered civil engineer.

Permeable paving, has emerged as an innovative and transformative solution, reshaping the way we approach the design and functionality of our roads and drainage systems. They are a sustainable alternative to traditional impervious surfaces and hold immense potential in

highway and drainage engineering. Unlike conventional pavement, which exacerbates stormwater runoff risk and contributes to urban heat islands, permeable paving allows water to infiltrate the surface at source, promoting natural drainage and reducing the strain on drainage systems.

Permeable paving comes in various types, each offering unique advantages tailored to specific project requirements. Porous asphalt, permeable concrete, permeable interlocking concrete pavers, and resin-bound gravel are among the most widely used options. These materials provide diverse solutions, allowing engineers to select the most suitable type based on factors such as traffic load, aesthetics, and regional climate conditions.

Key documents such as the CIRIA SuDS Manual (C753) and the British Standards BS 7533-13:2020 for concrete block permeable paving, provide essential guidelines and specifications for the calculation and design process.

Here are some key benefits of permeable paving:

  • Sustainable Drainage Systems (SuDS): Permeable paving aligns seamlessly with the principles of Sustainable Drainage Systems (SuDS), promoting environmentally friendly solutions. By facilitating the natural filtration of rainwater and reducing runoff, permeable pavements contribute to groundwater recharge and the preservation of local ecosystems. The use of Permeable paving also allows attenuation storage to be provided within the underlying pavement layer, reducing or removing the requirement for bespoke attenuation solutions.
  • Contamination Reduction: Permeable paving systems offer an added advantage by helping to reduce contamination in urban areas. The permeability allows pollutants to be effectively trapped by the sub-base or a geo-textile layer, preventing them from entering natural waterways. This not only safeguards local water quality but also supports efforts to combat environmental pollution, making permeable paving a responsible choice for drainage engineering.
  • Local Authorities’ Approval: As sustainable practices gain prominence in urban planning, local authorities are increasingly recognizing the benefits of permeable paving. Projects incorporating these innovative solutions often find favour during approval processes, fostering community-supported and environmentally conscious developments.

In the realm of highway and drainage engineering, permeable paving stands as a beacon of sustainable progress, transforming how we manage stormwater, enhance road safety, and contribute to the overall well-being of our environment. The diverse types of permeable paving, catering to specific engineering needs, further enhance its versatility and application.

  • Drainage Detailed Design Services
  • External Hardstanding Detailed Design Services

Civilistix engineers were appointed to provide civil engineering services in respect of the Old Winfresh Site, Essex. Our scope was to prepare full civils design packages for a ~5,000m2 service yard area to support the operations of the existing business as well as design remediation of the existing access road, refuelling area and general storage areas.

We Prepared a full gravity surface water drainage system encompassing linear drainage within the service yard, conveying runoff to an oil interceptor before being conveyed to a 250m3 geo-cellular storage tank before being released at 2.00 l/s for all events up to an including the 100 year plus 40% climate change event.

We designed the service yard slab based on the estimated 100yr Million Standard Axle (MSA) loading and prepared full external geometry informed by vehicle tracking analysis.

With regards to the access road and storage areas works, we prepared general arrangement plans identifying proposed resurfacing, re-levelling and kerbing works required for remediation as well as locations for new drainage positions.

We provided ongoing site support for the contractor including numerous site visits to ensure satisfactory delivery of the works to the client.


The Simple Index Approach (SIA) is a simplified risk-based method for selecting the appropriate sustainable drainage systems (SuDS) for the treatment of surface water runoff. The approach assigns pollution hazard indices for a given land use based on the expected pollution hazard level.

This approach is outlined in CIRIA C753 The SuDS Manual and the SIA tool helps to determine whether the proposed SuDS are in compliance with the approach. It is used to assess water quality management requirements and can be used across the UK.

Once the Simple Index Approach is done, the following are some examples of SuDS that can be used:

  • Green roofs: Vegetation is grown on the roof of a building to absorb rainwater and reduce runoff.
  • Rain gardens: A shallow depression in the ground that is planted with vegetation to absorb rainwater.
  • Permeable paving: Paving that allows water to pass through it and into the ground below

Our business is growing from strength to strength. As such we have a position available for a

Civil engineer
